Title: Transfer of designs to linoleum for subsequent cutting out - uses application of photographic emulsion subsequently exposed to light from enlarger
Inventor: DOTTERWEICH EWALD
IPC: G03C11/00
Filed: 1976-09-07
Abstract: The main patent describes a method of transferring designs to linoleum surfaces using optical enlargers. The enlarged design is then traced by hand and then cut out with a knife. In addition grooves are also cut in the surface and then filled with suitable colouring matter. The addition to the patent eliminates the difficulty of tracing the design by hand. This is done by coating the surface of the linoleum with photographic emulsion which is then exposed to the rays of light from the enlarger. The pattern is then developed for subsequent cutting and colouring.

Title: Reverse for manually operable speed change gearing - has progressively increasing and then constant resistance produced by spring during engagement of reverse
Inventor: MUELLER ROBERT
IPC: F16H63/20
Filed: 1976-10-07
Abstract: The reverse gear for manually operable speed change gearing in motor vehicles comprises a finger secured to a pivotally and axially movable operating shaft. The finger is movable for its tip to pass through a cut-out in an axially movable selector bar into a recess of a reverse gear operating fork. The movement is made in opposition to a spring. During movement through the cut-out the force of the spring progressively increases. Toward the end of that movement the resistance becomes constant to indicate to the user that the end of the selecting action is reached. The reverse gear can then be engaged in the usual way.

Title: Vacuum cleaner with integral lid - has slide push fastener with oblique surface at one end allowing lid to be raised
Inventor: GLONING GUNTER
IPC: A47L9/00
Filed: 1977-02-25
Abstract: Vacuum cleaner has an integral removable lid (21) provided with hinges (24-27). The lid closes with a slide push fastener (33). This slide push fastener has an oblique surface at one of its ends which allows the lid to be lifted off the vacuum cleaner housing when necessary, e.g. when a change of filter is required. The hinges and the fact that the lid is held in the closed position by a slide lock which permits it to remain attached to the main housing while open, or to be lifted off the housing altogether, does away with the need for springs and a spring snap fastening device.

Title: Vessel for protecting measuring instrument against high temps. - has thermal resistance increased by intensified utilisation of steam
Inventor: EMSCHERMANN HANS H
IPC: G12B17/06
Filed: 1977-05-05
Abstract: The parent patent describes a vessel for the protection of a measuring instrument against high temps., comprising a water vessel with steam outlet(s), enclosed in a heat insulating container. The vessel is modified to increase the thermal resistance and heat capacity of the protective vessel and thus increase the time constant of the temp. gradient. The water vessel which is connected thermally conducting to a protective chamber in which a Dewar flask houses a measuring instrument, is formed by a nest of boxes in which the water between the first two vapories first, forming a space without water. The vapour arising is deflected by baffle plates and escapes via pipe stubs into the heat insulation so as to cool it. In the insulating chamber, radiation screens are fitted, and steam outlet(s) are provided.

Title: Heat storage system with phase changing material - has flexible partitions ensuring stability when liq. medium solidifies, yielding heat
Inventor: GAWRON KLAUS
IPC: C09K5/06
Filed: 1977-05-05
Abstract: The heat storage system has several vessels holding heat storing material. The latter can be converted from solid to liquid phase. Heat is exchanged by one or more heat exchanging vessel walls. Each vessel holds also a heat transfer medium. A flexible, yielding partition wall is arranged between heat storing and heat transfer media. Contact faces are held constant during melting and especially also during solidification of the storage material. The heat transfer medium (5) is liquid at operating temperature and it does not evaporate. It is arranged in such quantities in the holding vessels that it completely fills on solidification of the heat storing material (3) the space between the partition wall and the vessel wall. The vessel has an expansion chamber for the heat transfer medium. Stratification of the heat storage material is prevented by using matrix material such as plastics foam or metal wool with open pores.
